IMPROVEMENT IN SEWING-MACHINE SHUTTLES.

TO ALL WHOM IT MAY CONCERN:

Be it known that we, EZEKIEL BOOTH and JOB A. DAVIS, both of Watertown,in the county of Jefferson, and State of New York, have invented certainnew and useful improvements in Sewing-Machine Shuttles and we do herebydeclare thet the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to theaccompanying drawings, making part of this specification, in whichFigure 1 is a side view of the shuttle.

Figure 2, a top view or plan.

Figure 3, a longitudinal section and Figure 4, a. top view, with thebobbin removed.

Similar letters of reference indicate corresponding parts in the severalviews.

This invention relates to the manner of securing the bobbin in theshuttle. The main part of the shuttle being made in the usual form, weinsert in the bottom thereof a longitudinal spring, one end of which issecured to the shuttle near the rear end, and the other end providedwith a socket or hearing for the end of the bobbin. In fig. 3 the bobbinZ1 is represented in its proper position, the front end bearing againstthe socket B, and held in place by the action of the spring 8. Thespring 8 may be let into a recess in the bottom of the shuttle, so as tobe out of the way of the bobbin. A recess is made in the front end ofthe shuttle large enough to admit the socket B, and allow the necessaryplay of the same. The spring s and socket B may be made of steel or anyother suitable metal. The advantages of this arrangement for securingthe bobbin consist in its. simplicity, cheapness, and durability. 1

Having thus described our improvement, what we claim as our invention,and desire to secure by Letters Patent, is i The longitudinal spring 8,with the socket B atta hed, for the purpose of securing the bobbin,constructed and operating substantially as set forth.
